Until 1993 complex surgery for children in Papua New Guinea (PNG) was usually conducted by general surgeons, or by overseas paediatric surgeons during ad hoc visits. There had been little coordination of these occasional international visits and no involvement in the surgical teaching program in the University Department of Surgery. Over eight years from July 1993 to July 2000, three Australian surgeons spent 33 weeks teaching paediatric surgery and paediatric urology, using lectures, tutorials and operative demonstration sessions. This paper is a report of the teaching and service provided by one surgeon (PAD) over 27 weeks in PNG and describes the development and training of the surgeon who will be the country's first qualified paediatric surgeon (MM). Other support given has been assistance with the publication of scientific papers, reviews of Masters' theses, the development of a proposal for investigation of the prevalence of renal tract anomalies and the development of protocols for the surgical management of anorectal anomalies and Hirschsprung's disease. In addition to this teaching, 311 children have had surgery during the 11 visits that form the basis of this report. The visits have been supported and funded by AusAID and the Royal Australasian College of Surgeons through the Medical Officer, Nursing and Allied Health Professional (MONAHP) and Pacific Islands Project (PIP) programs. An indication of the impact on the care of children with surgical diseases is evident from the improved skills and the changed referral patterns over the eight years.

Traditionally, urologists recommend an interval of at least 4 weeks after prostate biopsy before radical prostatectomy. The aim of our study was to evaluate whether the interval from prostate biopsy to radical prostatectomy affects immediate operative outcomes, with a focus on differences in surgical approach. The study population of 1,848 radical prostatectomy patients was divided into two groups according to the surgical approach: open or minimally invasive. Open group included perineal and retropubic approach, and minimally invasive group included laparoscopic and robotic approach. The cut-off of the biopsy-to-surgery interval was 4 weeks. Positive surgical margin status, operative time and estimated blood loss were evaluated as endpoint parameters. In the open group, there were significant differences in operative time and estimated blood loss between the <4-week and > or =4-week interval subgroups, but there was no difference in positive margin rate. In the minimally invasive group, there were no differences in the three outcome parameters between the two subgroups. Multivariate analysis revealed that the biopsy-to-surgery interval was not a significant factor affecting immediate operative outcomes in both open and minimally invasive groups, with the exception of the interval > or =4 weeks as a significant factor decreasing operative time in the minimally invasive group. In conclusion, performing open or minimally invasive radical prostatectomy within 4 weeks of prostate biopsy is feasible for both approaches, and is even beneficial for minimally invasive radical prostatectomy to reduce operative time.

OBJECTIVE: To explore the general characteristics of medical negligence in surgery in order to provide the reference for forensic practices. METHODS: One hundred and twelve cases of medical negligence in surgical department were retrospectively analyzed in Fada Institute of Forensic Medicine and Science from 2008 to 2010. RESULTS: The common types of medical negligence cases in the surgery were improper operation procedure (28.57%), failure of consent (26.79%), and inadequate monitoring (22.32%). The results of complications included disability or functional impairment (61.61%), death (31.25%) and transient impairment with no obvious adverse reactions (7.14%). The most common roles played by the medical negligence cases were minor role (26.79%), equal role (19.64%), and slight role (14.29%). CONCLUSION Significant attention should be paid to the operation procedure, consent, and monitoring. It should be cautious to not make assessment on involvement degree of medical negligence.

OBJECTIVETo investigate the surgical treatment and prognosis for recurrent colon cancer after curative resection.

METHODSThe clinical data of 102 recurrent colon cancer cases from January 1997 to December 2005 were analyzed retrospectively. Obtained data were analyzed by Statistical Package for the Social Sciences (Release 11.5, SPSS, Inc). The related factors were underwent chi2 analysis,survival analysis were estimated using the Kaplan-Meier method and compared using the Log-rank test. COX regression was used in multivariate analysis.

RESULTSUnivariate analysis revealed that obstruction of primary tumors, CEA level before reoperation, number of recurrence, time of recurrence, and reoperation type were significant statistically. COX regression analysis revealed that number of recurrence, reoperation type was the most important prognostic factor.

CONCLUSIONThe recurrent colon cancer still need active surgical treatment in order to prolong the survival time.

OBJECTIVETo evaluate the feasibility, safety and short-term clinical outcomes of robot-assisted minimally invasive esophagectomy (RAMIE).

METHODSClinical data of 17 patients with esophageal cancer who received RAMIE between April 2016 and July 2016 were analyzed retrospectively.

RESULTSThe age of the patients ranged from 44 to 83. Six patients received neoadjuvant radiochemotherapy while 11 patients underwent surgery alone. All patients were performed by the robot-assisted thoraco-laparoscopic minimally invasive esophagectomy. In-hospital mortality was 0%. None was converted to open transthoracic or laparotomy approach. In the neoadjuvant radiochemotherapy group, 3 patients received pathological complete response while 2 patients were stage II(A and 1 patient was stage II(B. In the surgery alone group, 1 patient was stage I(A, 3 patients were stage II(A, 5 patients were stage II(B, 1 patient was stage III(A and 1 patient was stage III(B. The mean operation time was 195 minutes (range 145 to 305 minutes). The mean blood loss was 60 ml (range 30 to 200 ml). Mean lymph node harvest was 28 nodes. The rate of radical resection was 100%. Median ICU stay was 4.5 days (range 1 to 36 days), and median overall postoperative hospital stay was 15.2 days(range 9 to 45 days). Postoperative complication occurred in 4 (23.5%) patients, including 3 (17.6%) of lung lesion, 2 (11.8%) of hoarseness, 1 (5.9%) of chylothorax, while no anastomotic leakage and arrhythmia was observed.

CONCLUSIONRAMIE for esophageal cancer is feasible and safe with favorable early outcomes.

OBJECTIVE: To discuss the feasibility of single-site robotic surgery for benign gynecologic tumors and early stage gynecologic cancers. METHODS: In this single institution, prospective analysis, we analyzed six patients who had undergone single-site robotic surgery between December 2013 and August 2014. Surgery was performed using the da Vinci Si Surgical System. Patient characteristics and surgical outcomes were analyzed. RESULTS: Single-site robotic surgery was performed successfully in all six cases. The median patient age was 48 years, and the median body mass index was 25.5 kg/m2 (range, 22 to 33 kg/m2). The median total operative time was 211 minutes, and the median duration of intracorporeal vaginal cuff suturing was 32 minutes (range, 22 to 47 minutes). The median duration of pelvic lymph node dissection was 31 minutes on one side and 27 minutes on the other side. Patients' postoperative courses were uneventful. The median postoperative hospital stay was 4 days. No postoperative complications occurred. CONCLUSION: When used to treat benign gynecologic tumors and early stage gynecologic cancers, the single-site da Vinci robotic surgery is feasible, safe, and produces favorable surgical outcomes.

OBJECTIVETo summarize the perioperative and postoperative complications follow laparoscopic intersphincteric resection (LapISR) in the treatment of low rectal cancer and their management.

METHODSAn observational study was conducted in 73 consecutive patients who underwent LapISR for low rectal cancer between June 2011 and February 2016 in our hospital. The clinicopathological parameters, perioperative and postoperative complications, and clinical outcomes were collected from a prospectively maintained database. Perioperative and postoperative complications were defined as any complication occurring within or more than 3 months after the primary operation, respectively.

RESULTSForty-nine(67.1%) cases were male and 24(32.9%) were female with a median age of 61(25 to 79) years. The median distance from distal tumor margin to anal verge was 4.0(1.0 to 5.5) cm. The median operative time was 195 (120 to 360) min, median intra operative blood loss was 100 (20 to 300) ml, median number of harvested lymph nodes was 14(3 to 31) per case. All the patients underwent preventive terminal ileum loop stoma. No conversion or hospital mortality was presented. The R0 resection rate was 98.6% with totally negative distal resection margin. A total of 34 complication episodes were recorded in 21(28.8%) patients during perioperative period, and among which 20.6%(7/34) was grade III(-IIII( according to Dindo system. Anastomosis-associated morbidity (16.4%,12/73) was the most common after LapISR, including mucosa ischemia in 9 cases(12.3%), stricture in 7 cases (9.6%, 4 cases secondary to mucosa necrosis receiving anal dilation), grade A fistula in 3 cases (4.1%) receiving conservative treatment and necrosis in 1 case (1.4%) receiving permanent stoma. After a median follow up of 21(3 to 60) months, postoperative complications were recorded in 12 patients (16.4%) with 16 episodes, including anastomotic stenosis (8.2%), rectum segmental stricture (5.5%), ileus (2.7%), partial anastomotic dehiscence (1.4%), anastomotic fistula (1.4%), rectovaginal fistula (1.4%) and mucosal prolapse (1.4%). These patients received corresponding treatments, such as endoscopic transanal resection, anal dilation, enema, purgative, permanent stoma, etc. according to the lesions. Six patients (8.2%) required re-operation intervention due to postoperative complications.

CONCLUSIONAnastomosis-associated morbidity is the most common after LapISR in the treatment of low rectal cancer in perioperative and postoperative periods, which must be strictly managed with suitable methods.

OBJECTIVEIntertrochanteric femur fracture is a common injury in elderly patients. The dynamic hip screw (DHS) has served as the standard choice for fixation; however it has several drawbacks. Studies of the percutaneous compression plate (PCCP) are still inconclusive in regards to its efficacy and safety. By comparing the two methods, we assessed their clinical therapeutic outcome.

METHODSA total of 121 elderly patients with intertrochanteric femur fractures (type AO/OTA 31.A1-A2, Evans type 1) were divided randomly into two groups undergoing either a minimally invasive PCCP procedure or a conventional DHS fixation.

RESULTSThe mean operation duration was significantly shorter in the PCCP group (55.2 min versus 88.5 min, P<0.01). The blood loss was 156.5 ml±18.3 ml in the PCCP group and 513.2 ml±66.2 ml in the DHS group (P<0.01). Among the patients treated with PCCP, 3.1% needed blood transfusions, compared with 44.6% of those that had DHS surgery (P<0.01). The PCCP group displayed less postoperative complications (P<0.05). The mean American Society of Anesthesiologists score and Harris hip score in the PCCP group were better than those in the DHS group. There were no significant differences in the mean hospital stay, mortality rates, or fracture healing.

CONCLUSIONDue to several advantages, PCCP has the potential to become the ideal choice for treating intertrochanteric fractures (type AO/OTA 31.A1-A2, Evans type 1), particularly in the elderly.
